Rebar spacing adjuster

Abstract

The invention discloses a rebar spacing adjuster. The adjuster comprises a casing pipe and a screw, wherein a strip-type slot is formed in the casing pipe in the length direction, one end of the screw extends into the casing pipe and is provided with a first limit part, and the first limit part extends out of the strip-type slot; the screw body, which does not extend into the casing pipe, of the screw is sleeved with a nut, and a second limit part is arranged at one end, far away from the nut, of the casing pipe. Production materials of the adjuster can be directly taken from a construction site, and the adjuster is very low in cost, simple in structure, easy to manufacture, low in fault rate, safe, reliable, energy-saving, environment-friendly and convenient to operate. The adjuster can be used for replacing manual operation of rebar engineering construction, the effect of the construction progress due to deviation is avoided, and the adjuster plays a great role in engineering rushing and progress acceleration; the adjuster can be produced according to different rebar spacing size requirements and different length sizes, is widely applicable of adjustment of rebar spacing of multiple structural elements and is worth wide popularization and use in the industry.

Description

technical field [0001] The invention relates to the field of building construction tooling, in particular to a steel bar spacing adjuster. Background technique [0002] At present, most of the steel bars such as wall columns, beams, and slabs in building construction are bound manually. The requirements for the binding spacing of steel bars and the thickness of concrete cover are particularly strict during acceptance. The spacing of steel bars exceeding the allowable deviation must be adjusted in place. If it is the binding of steel bars between the foundation floor and the floor, there are no stirrups between the main bars, and the spacing of the steel bars is relatively easy to control; and for the binding of steel bars such as columns and beams, the spacing between the main bars is completely tied to the main bars by tie wires. Binding together, it is very difficult to adjust the spacing of the main ribs after binding. [0003] Since the binding of the main bars and stir...

Problems solved by technology

Usually the operator first beats with steel pipes or pries with steel bars, but the result is very unsatisfactory. At present, there is no suitable tool to adjust the spacing between steel bars, so they have to rework to loosen the wires, remove them, re-bind them, and tie them up. There may still be similar problems in the future; delays in work and time will seriously affect the construction progress
